so a friend of mine has a 2003 Denali with cd player, i think its the 6 disk. anyways, she wants to know if you can go from OEM cd to OEM Nav.
She wants to keep the Onstar..
So the question is, can it be done? is it worth it? or should she just get an aftermarket deck with Nav and buy the aftermarket mods to keep the factory speakers and Onstar?
